General Hydroponics is popular and kinda cheap. Flora Bloom is their flowering nute. It's what the Lucas formula was based on. Lots of people love Fox Farms, Tigerbloom.
Lots of people have issues with Fox Farms too. If you're growing in soil then stay simple and get yourself a Humic/Fulvic organic tea. Just google it and choose one that you think has the best advertising I guess. General Hydroponics makes one called Nectar, or something to that effect.
